U-2 Avionics Technician explains why Dragon Lady pilots breathe pure oxygen for as much as 14 hours straight
The U-2
Built in complete secrecy by Kelly Johnson and the Lockheed Skunk Works, the original U-2A first flew in August 1955. Early flights over the Soviet Union in the late 1950s provided the president and other US decision makers with key intelligence on Soviet military capability. In October 1962, the U-2 photographed the buildup of Soviet offensive nuclear missiles in Cuba, touching off the Cuban Missile Crisis. In more recent times, the U-2 Dragon Lady has provided intelligence during operations in Korea, the Balkans, Afghanistan, and Iraq. When requested, the U-2 also provides peacetime reconnaissance in support of disaster relief from floods, earthquakes, and forest fires as well as search and rescue operations.

The U-2R, first flown in 1967, was 40 percent larger and more capable than the original aircraft. A tactical reconnaissance version, the TR-1A, first flew in August 1981 and was structurally identical to the U-2R. The last U-2 and TR-1 aircraft were delivered in October 1989; in 1992 all TR-1s and U-2s were designated as U-2Rs. Since 1994, $1.7 billion has been invested to modernize the U-2 airframe and sensors. These upgrades also included the transition to the GE F118-101 engine which resulted in the re-designation of all Air Force U-2 aircraft to the U-2S.
U-2 pilots breathe pure oxygen for as much as 14 hours straight
Despite all these upgrades, one thing that hasn’t changed much at all over the years is oxygen.

‘[U-2 pilots] breathe pure oxygen for as much as 14 hours straight,’ Damien Leimbach, former USAF Avionics Technician on U-2 aircraft, says on Quora.
‘The plane flies at extreme altitudes (above 70K ft) which many people know. What most people don’t know is that the cockpit is not a pressure vessel. Look at the three panels under the windscreen in this photo.

‘Opening any of those up would allow a maintainer to look directly into the cockpit. The only thing holding the air inside is a thin smear of sealant, and some screws for the panel. As a result, the cockpit is only pressurized to the equivalent of about 29k ft, which for reference is roughly equal to standing at the top of Everest.
‘Why? To save weight. Putting a pilot in a space suit weighs less than building a pressure vessel into the plane.
U-2 pilots pre-breathing pure oxygen

‘You see that suitcase close to them? Yeah, that’s not their spare underwear and a toothbrush. It’s a liquid oxygen supply. They just spent an hour or more like this,

‘pre-breathing pure oxygen to purge his system of nitrogen.’
As highlighted above, one thing that hasn’t changed much at all over the years is oxygen: in fact, pre-breathing took place in the 1950s just like it takes place today.
Leimbach explains;
‘Just like scuba divers, rapid decompression in an emergency could cause the bends. So, the pilot will spend an hour or two before a mission taking a nap and breathing pure oxygen, then hooking up to the LOX case for the ride out to the jet, where PSD (physiological support division) will then connect him to the liquid oxygen supply on the jet. Then they get to spend the next 8–12 hours continuing to breathe pure oxygen during the mission. They do NOT mix the pure oxygen with air. That would defeat the purpose of the nitrogen purge. Anyone suggesting that this is somehow harmful or fatal to pilots needs to stop relying so much on bots so write her answers.
‘Here is a crew chief servicing the LOX tanks on the U-2.’

End Times
Faster and Harder :: By Daymond Duck Published on: June 26, 2022
I have known Christians that didn’t seem to know anything about Bible prophecy to say, “I know this; we are one day closer to the return of Jesus today than we were yesterday.”
No one can deny that each day moves the world one day closer to the return of Jesus, but people need to realize that major prophecies are shaping up, and they appear to be on steroids.
Biblically speaking, wars and rumors of wars, famine, inflation, natural disasters, world government, tracking all buying and selling, etc., are happening like birth pains (coming faster and harder).
They appear to be unstoppable (and very well could be because every word of Bible prophecy will be fulfilled).
Consider these recent events and reports:
One, concerning natural disasters: several years of drought and growth have caused the two largest water reservoirs in the U.S. to reach their lowest levels since they were built (Lake Mead and Lake Powell).
On June 17, 2022, it was reported that the Bureau of Reclamation has given the seven states in the Colorado River system 60 days to draft an emergency plan to cut their water usage in the next 12 months or the Bureau of Reclamation will declare an emergency and make the cuts that need to be made.
Commissioner Camille Touton told a group of U.S. Senators, “The challenges we are seeing today are unlike anything we have seen in our history.”
(More: On June 21, 2022, it was reported that flooding in southern China has forced the evacuation of hundreds of thousands of people and caused more than $250 million in damage to date.)
(More: On June 22, 2022, it was reported that a 6.1 earthquake in eastern Afghanistan has killed about 1,000, injured about 1,500, and many families are missing.)
Two, concerning Israel’s prosperity and the Battle of Gog and Magog: on June 15, 2022, Israel signed an agreement with the EU to send liquified natural gas to Europe, and that will be a major blow to Russia’s economy.
Israel will send the liquified natural gas to Egypt, and it will flow on to Europe over Egyptian pipelines.
In addition to getting a big chunk of Russia’s business, Israel will have improved relations with the EU and Egypt.
Amir Tsarfati called this blow to Russia “a countdown to the Battle of Gog and Magog.”
Time will tell, but Russia’s need for wealth and Israel’s prosperity clearly fit Bible prophecy.
Three, concerning the Battle of Gog and Magog or perhaps the destruction of Damascus in one night: last week, I reported that Israeli rockets struck several targets near Damascus on June 10, 2022, and there was significant damage to civilian and military runways at the Damascus International Airport.
The airport was using a Russian-made radar system that was damaged in the attack.
Syria wants Russia to repair the radar system so planes can land and take off, but Russia will only repair it if Russia is given control of the airport.
Iran has been controlling the airport and is not likely to let Russia have it.
It will be interesting to see how this turns out.
Four, concerning the destruction of Damascus in one night (Isa. 17): on June 15, 2022, it was reported that an Israeli official told Syrian Pres. Assad that he risks losing the Damascus International Airport if he continues to allow Iranian planes to land there with weapons and supplies for use against Israel.
(More: The next day, June 16, 2022, it was reported that the Israeli official also told Assad that Israel reserves the right to bomb his palace if he continues to allow Iranian planes to land at the Damascus International Airport with weapons and supplies for use against Israel. This could turn out to be the destruction of Damascus in one night– Isa. 17.)
Five, concerning the Israeli government: on June 20, 2022, Israeli Prime Min. Naftali Bennett and Alternate Prime Min. Yair Lapid announced that they will bring a vote to dissolve their government in one week and schedule an election of a new government for Oct. 25, 2022.
Former Prime Min. Netanyahu will seek the nomination of his Likud Party, but his enemies will desperately try to stop him, and who will run and win remains to be determined.
(More: On June 21, 2022, it was reported that Ayelet Shaked, a member of Prime Min. Bennett’s party, told Netanyahu she will switch to his party, giving him enough members to form a government if he wants to avoid another election. The report did not say what Netanyahu will do.)
Six, concerning wickedness as in the days of Noah: more than 20 crisis pregnancy centers have been damaged by graffiti, smashed windows and arson since Politico published the Supreme Court’s draft opinion concerning Roe v. Wade in early May.
A terrorist group that calls itself Jane’s Revenge has taken credit for the crimes and threatened to take “increasingly drastic measures” in the future.
This is literal domestic terrorism, and the Biden administration is completely ignoring it (like ignoring open borders, ignoring Antifa and BLM crimes, ignoring the fact that some prosecutors refuse to prosecute known criminals, etc.), but they jailed Trump supporters that entered the Capitol on Jan. 6, investigated parents that spoke out at school board meetings against teaching CRT, the gay agenda, etc.
There is unequal justice in the Biden administration and America’s justice system.
Seven, Concerning the days of Lot: on June 21, 2022, it was reported that Pres. Biden has signed an executive order to help young teens get transgender surgeries, to help biological girls 8-10 years get puberty blockers, to help biological boys 10-15 years old get puberty blockers, to allow transgender students to use the bathroom or locker room of their choice at school, to prohibit counseling against transitioning to a different gender, etc.
How much worse does America have to get to be as bad as Sodom and Gomorrah?
When will our holy, just, and patient God act?
Eight, on June 16, 2022, it was reported that the Biden administration may declare a national public health emergency so doctors can perform abortions in states where they are illegal if Roe v. Wade is overturned.
Biden may also allow doctors to perform abortions on military bases in those states.
So, Biden is looking for ways to let doctors keep killing babies regardless of what the U.S. Supreme Court or individual state laws say.
Americans are getting a glimpse of what life will be like under the coming wicked and lawless world government (equal justice won’t exist).
Nine, concerning every eye seeing the body of the Two Witnesses lying in the street in Jerusalem (Rev. 11:8) and every eye seeing the Second Coming of Jesus (Rev. 1:7): the Federal Communications Commission (FCC) has granted SpaceX permission to put 12,000 Starlink satellites in orbit and is considering SpaceX’s application to put up to 30,000 additional satellites in orbit.
Elon Musk (head of SpaceX) wants to put about 42,000 satellites in orbit so every person on earth will have access to the Internet.
On June 17, 2022, it was reported that SpaceX has put about 3,000 satellites in orbit to date (SpaceX can put 60 satellites in orbit with just one rocket).
If this is the fulfillment of the prophecies, SpaceX only needs to get all the satellites in orbit by the middle of the Tribulation Period.
Ten, concerning inflation, lying and deceit: I am not an attorney, but as I understand a June 15, 2022, article:
In Jan. 2021, Pres. Biden signed an executive order banning new federal oil and gas leasing in the U.S.
In Mar. 2021, several states filed a lawsuit to set aside Biden’s executive order.
In June 2021, the U.S. District Court for the Western District of Louisiana ordered Pres. Biden to keep selling new federal oil and gas leases until the case is settled.
Despite the court order, during the next 10 months, the Biden administration didn’t sell even one oil or gas lease.
In Apr. 2022, the states asked the U.S. District Court to permanently stop the Biden administration from banning the sale of new federal oil and gas leases.
On June 15, 2022, it was reported that the Biden administration asked a federal court to let Biden keep banning the sale of new oil and gas leases.
The high price of gasoline and diesel fuel is contributing to inflation; the high price of food; looming energy and fertilizer shortages; soaring utility bills, etc.
Because inflation is soaring, the feds are raising interest rates, the stock market is declining, and some experts are predicting a recession.
At the same time that Biden is blaming the energy crisis on Putin and the big oil companies, he is going to court to hold down oil and gas production in the U.S.
From a prophetic standpoint, it looks like Biden is setting the stage for the Four Horsemen of the Apocalypse to ride soon.
(More: At the same time that Biden is going to court to reduce the production of oil and gas in the U.S., he will be meeting with Saudi Arabia to get the Saudis to increase their production of oil and natural gas. If Biden is not deliberately weakening the U.S. to bring it into the New World Order, why is he doing this? It truly looks like the deliberate weakening of America is part of the Build Back Better scheme.)
Eleven, concerning food shortages: last week, multitudes of cattle died in Kansas, and the cause has been a matter of rampant speculation.
I can’t settle the issue as to why the cattle died, but on June 17, 2022, it was reported that more than 10,000 cattle died.
Pray that this is the end of the problem.
Twelve, concerning inflation and electrical shortages: most residents of Illinois have been notified that their electric bill will rise about 50% starting this month (June 2022), and some have been asked to reduce the amount of electricity they are using to help prevent brownouts.
Thirteen, concerning fuel shortages: diesel fuel is now about $6 per gallon (up about 75% in the last 12 months).
Fourteen, concerning the election: on June 18, 2022, about 5,100 delegates and alternates met at the Texas Republican convention to approve their Party Platform.
After watching Dinesh D’Souza’s documentary titled “2000 Mules,” the group approved a measure that says Pres. Joe Biden “was not legitimately elected.”
(More: On June 20, 2022, Bob Adelmann (regular contributor to The New American) wrote that he watched “2000 Mules,” and he believes Trump won the Electoral College Vote in a landslide (by more than 70 votes). Adelmann noted that the evidence presented in “2000 Mules” has caused the ex-Mayor of San Luis, Arizona, to plead guilty to forgery, conspiracy, and ballot abuse, and to offer evidence as part of a plea bargain. Officials are investigating her claim.)
Fifteen, on June 16, 2022, Dr. Michael Brown (Radio Host, Professor, author, Christian Zionist) posted an excellent article titled “How the Triumph Of LGBTQ+ Activism Has Negatively Impacted the Church.”
The article is short, filled with great advice, and well worth one’s time.
It can be found at https://stream.org/how-the-triumph-of-lgbtq-activism-has-negatively-impacted-the-church/
In my words, here are just 3 of Dr. Brown’s points:
About 30 years ago, Christianity was respected, and homosexuality was disdained, but now gays are celebrated, and the Church is largely ridiculed.
Many (especially young people) now believe gay is good and the Church is bad, so they are leaving the Church.
Past generations proudly called themselves Christians and would have been insulted to be called gay, but Christians are openly mocked by the current generation, and gays are celebrated.
According to Dr. Brown, “The problem for true followers of Jesus is that the Bible hasn’t changed, which means that God is still against homosexual practice and identity. And so, if we want to be in solidarity with the Lord, we will find ourselves at odds with the prevailing culture.”
(My opinion: This rift between believers and the prevailing culture is behind the attacks on Churches and pro-life centers that oppose abortion. It will worsen, and it will eventually lead to the persecution of those that are faithful.)
Sixteen, concerning a digital currency (a system for government to track all buying and selling and control everyone): on June 17, 2022, Federal Reserve Pres. Jerome Powell announced that the Fed does plan to develop a “Digital Dollar” (sometimes called a Central Bank Digital Currency—CBDC).
The Fed will control the digital currency and have the authority to freeze accounts and seize funds (deny you access to your money and take it if they don’t approve of what you say and do).
Finally, are you Rapture Ready?
If you want to be rapture ready and go to heaven, you must be born again (John 3:3). God loves you, and if you have not done so, sincerely admit that you are a sinner; believe that Jesus is the virgin-born, sinless Son of God who died for the sins of the world, was buried, and raised from the dead; ask Him to forgive your sins, cleanse you, come into your heart and be your Saviour; then tell someone that you have done this.
